Then we might have some other problems accessing that RAID. When
configured as a large 2620354MB logical drive (no logical drive partitions):

Opened disk da1 -> 5
[...]
Using 1 logical drive with two partitions mapped to two LUNs (resulting
in da1 and da2 in FreeBSD) works perfectly.
BTW: I'm actually running a nearly-GENERIC kernel 5.4-RELEASE here, just
with
options SMP
device ccd
added. Maybe I will need some other options? What about GEOM?
But for me it smells more about the SCSI-protocol between RAID and
Controller (Adaptec 39160), something about LBA-64?
Maybe running -current will give me this feature?
Running ccd upon a partitioned RAID is "A Bad Idea[tm]".
Any pointers to documentation? Maybe I just need some deeper
knowledge about whats going on here.
